Of late I have had some issues with the comments and how comments are handled by the blog. Out of the blue I found comments on older posts turned off, comment moderation turned on for all posts, and “login prior to comment” turned on.
In researching the issue, I found this to be not unusual and related to one of the plugins interacting with the theme. I manually turned comment moderation off and opened up the comments again (no login required), but will have to tweak the MySQL database to fix the “comments off” issue. Then I am going to have to find out which plugin is affecting the theme.
However, it is not all a bad thing as I need to make the blog theme more closely match the theme of the rest of the website. This would also include upgrading the theme to work with the updated versions of WordPress.
